Battery Pack BU-5
The BU-5 can be installed underneath the 505K or beside it. The BU-5
uses the same type of enclosure as the 505K and is mounted in the same
way. The BU-5 has a “cable tail” which plugs into the 505K. The input
wiring is then connected to a socket on the BU-5.
The lid of the BU-5 can be rotated to suit installation.
A second BU-5 can be connected to the first in a similar manner. The
input wiring for the 505K is then connected to the socket on the second
BU-5.
All plugs and connectors should be waterproofed with waterproofing
tape.
Check the label on the back of the BU-5 to make sure that it has been factory-set to 9V.
The BU-5 takes six alkaline AA batteries - such as Duracel MX1500 or Eveready E91. Do
not use rechargeable batteries in the BU-5 as their self discharge life is short. The
temperature rating of the BU-5 depends on the battery type - for alkaline batteries, this is
